Clifford and Evan,
I recently came across something similar to this problem when assisting
one of my friends in setting up their linux pppd system.

Eventually, after sorting out some of the points you have already
mentioned, we found out that there was also a modem configuration
problem.  Apparently the modem we were using (can't remember the brand
unfortunately), was configured by default to echo all information sent to
the other modem.  This created some confusion as pppd could never ACK the
other pppd's commands properly!

We turned off this feature(?!) and everything worked fine.

I thought that pppd might return a serial line looped back error message
but for some reason it didn't.  I may not understand the circumstances for
that particular error properly though.

Perhaps this could be the problem? It would be worth a look anyway.

Hope this is of some help.

Regards
Paul

Hi all,

I had these problem some times ago with an EXTERNAL USR ROBOTICS MODEM.

I solved this trouble by sending this init string to the mode: AT&F1

The USR Modem seems to have several factory configs (3), and the ATZ init string that i was sended
first to the modem seems to call a bad factory profile....the modem, if connected to my ISP, was not able to receive
LCP responses. (ATE0/1, ATV0/1?).

Try it ... it has works for me,

eric.
